This-invention relates to end stops for separable iastener stringers,and more particularly the invention relates to an end stop wherein aplurality of links at adjacent stringer ends are Joined together, and toeach other, by means engaging coupling ends of said links to impartfollowing description when taken together with the accompanying drawingin which certain embodiments ofthe invention are disclosed, and in whichthe separate parts are designated by suitable reference characters ineach of the views and in which:

Fig; 1 is a plan view of an end stop showing one adaptation of ourinvention, and having part of the structure broken away; and l Fig. 2 isa partial section substantially on the line 2-2- of Fig. 1.

In the construction of end stops for separable fasteners to be used onclosures wherein the stringer tapes are brought together beyond the endlinks, adjacent the wide or web end of the slider it has been customaryto employ supplemental means engaging the tapes to draw the sametogether in the desired manner. Such supplemental means permanentlyattached to the tapes can be removed only with difliculty, and suchremoval generally results in damage to the tape and impairment ofsubsequent use of the fastener.

It is the purpose of the present invention to dispense with supplementaldevices attached to the tapes and to unite the tape ends to form an endstop to cooperate with the web end of a slider by utilizing meansdirectly engaging a plurality of links of each stringer in a manner toimpart a substantially arcuate contour to said links in drawing towardeach other those farthest removed from the slider.

In Fig. 1 of the drawingwe havexshownend portions of stringer lengths IIand H having links I! and I8 arranged along opposed edges thereof. ersare on a continuous tape it, having a beaded edge II for supporting thelinks I! and it and Y which is folded back upon itself in the mannerindicated to bring the two stringers into Juntaposition. It will beunderstood in this'connection that the invention applies equally to aconstruction wherein the stringers are arranged on independent tapes.The slider i is shown As shown in the drawing, the stringin operativeengagement with the links I! and IS, a part of the slider being brokenawayto show the web ll thereof.

The coupling ends it of the links I: and I! are provided with aperturesit passing therethrough in a direction parallel to the beaded edge I! ofthe tape. In the construction shown in the drawing the apertures ll formin conjunction with the projections 20, the, inter-locking'means betweenlinks I! and "of: co-acting stringers, said links being double acting.It will be understood, however,-that the invention is not limited tothis construction, but links of any type and kind may be fashioned toprovide apertures such as the apertures I! through the coupling endsthereof.

Arranged in the apertures II of a plurality of links I! and I3 adjacentthe ends of the stringers is a strand-like member II adapted to draw thelinks into an arcuate conto'ur substantially as indicated in thedrawing. For purposes of illustration the member II has been indicatedthesubstantially arcuate contour by the member II.

While for purposes of illustration the member 2| has been shown anddescribed as a wire. it will be understood that any strand-like membermay be employed having means equivalent to the oflsets 22 for retainingthe member in connection with a plurality of links I! and II, whileatthe same time drawing the-coupling ends ll of the links toward eachother in the manner indicated, thereby bringing the beaded edge portionsI! of the stringers into lusts-position beyond the end links a and its.4

In the construction shown in the drawing wherein the stringers are on asingle continuous tape ll the foldedportion Ila of the tape may besecured'to the main portionof the tape I by a line of stitching It,which lineof stitch- .ing will operate to retain the beaded edges II industs-position. It will be understood in this connection that if thestringers constituted sep arate tapes, .it might be desirable to stitcht0" V gether the beaded edges l5 beyond the end links l2a, his insubstantially the position of the line of stitching 23. 'Such stitchingwould not constitute an essential part of the end stop construction, butwould merely serve to maintain alignment of the tapes beyond the endstop.

' The showing in the drawing constitutes but one adaptation of ourinvention, and it will be understood that it is within the scope of ourinvention to employ any means for coupling and drawing together-aplurality of links at the ends of adjacent stringers to impart to saidlinks a substantially arcuate contour while at the same time forming aclosed loop between said stringers which is adapted to be closelyengaged by the stringers having apertures formed longitudinally claim asnew and desire to secure by Letters Patv ent is: g

1. An end stop for separable fasteners adapted to be engaged by the webend of a slider in the fully closed position thereof on the fastener,said end stop comprising means directly engaging a. plurality of linksat end portions of adjacent stringers and supporting said links in asubstantially arcuateclosed loop contour.

2. An end stop for separable fasteners adapted to be engaged by the webend of a slider in the fully closed position thereof on the fastener,said end stop comprising means directly engaging a.

of said stringers, means extending through said apertures adapted tojoin the coupling portions of said links, and means retaining said firstnamed means against accidental displacement from said links.

6. In separable fasteners employing stringers, said stringers comprisinglinks spaced longitudinally of a tape edge, the links having couplingportions protruding beyond the tape edges, the coupling portions of thelinks of each stringer having apertures extending there-through and astrand-like coupling element arranged in the apertures of predeterminedlinks of both stringers for joining said stringers.

'7. In separable fasteners employing stringers, said stringerscomprising links spaced longitudinally of a tape edge, the links havingcoupling portions protruding beyond the tape edges, the couplingportions of the links of each stringer having apertures extendingthere-through, a

. strand-like coupling element arranged in the plurality of links at endportions of adjacent I 4. An end stop for separablefasteners adapted tobe engaged by the web end of a slider in the fully closed positionthereof on the fastener, said end stop comprising means directlyengaging a plurality of links at end portions of adjacent stringers andsupporting said links in a substantially .arcuate closed loop contour.means retaining said first named means against displacement from saidlinks, and said first named means comprising a strand-like memberarranged in apertures in the coupling end portions of said links, saidmember assuming a substantially U shaped contour, and said second namedmeans comprising offset ends on said member preventing removal of thelinks therefrom.

5. A closed loop end stop for separable fasteners of the classdescribed, said end stop com prising a plurality of end links onadjacent links of each stringer and bridging adjacent links of saidstringers for uniting said opposed stringers while maintaining saidlinks disengaged from each other.

9. The combination with the coupling end portions of the links ofopposed stringers of a separable fastener, of means engagingpredetermined links of each stringer and bridging adjacent links of saidstringers for uniting said opposed stringers, said means comprising a Ushaped member engaging recessed portions of said links, and meansretaining said member against displacement from said links.
